This document describes an ultra-low capacitance ElectroStatic Discharge (ESD) protection diode, packaged in SOT23, designed to protect high-speed data lines from ESD and other transient damage.
The Philips PESDxU1UT series consists of unidirectional ElectroStatic Discharge (ESD) protection diodes designed for high-speed data lines. These devices feature ultra low diode capacitance (Cj=0.6 pF) and are housed in a small SOT23 (TO-236AB) plastic surface-mounted package. They are intended to protect lines from damage caused by ESD and other transients, with a maximum peak pulse power up to 200 Ws.
| Peak pulse power | up to 200 Ws |
|---|---|
| ESD protection voltage (IEC 61000-4-2) | > 23 kV |
| Package type | SOT23 |
| Reverse stand-off voltage (PESD3V3U1UT) | 3.3 V |
| Peak pulse current (PESD24VU1UT) | 3 A |
It is used for 10/100/1000 Ethernet, LAN equipment, FireWire, and high-speed datalines.
Connect V/O line 1 to device 1/pin 2 and device 2/pin 1, and V/O line 2 to device 1/pin 1 and device 2/pin 2.
